1. Base your answer to the following question on the diagram below, which shows models of two types of earthquake waves.
Model A best represents the motion of earthquake waves called
1)
2)
3)
4)
S-waves (shear waves) that travel slower than P-waves (compressional waves) shown in model B
P-waves (compressional waves) that travel faster than S-waves (shear waves) shown in model B
P-waves (compressional waves) that travel slower than S-waves (shear waves) shown in model B
S-waves (shear waves) that travel faster than P-waves (compressional waves) shown in model B
2. A P-wave takes 5 minutes to travel from the epicenter of an
earthquake to a seismic station. Approximately how many minutes
will it take an S-wave to travel that same distance?
1) 15 min
2) 12 min
3) 9 min
6. Base your answer to the following question on the map below. The
map shows point X, which is the location of an earthquake epicenter,
and point A, which is the location of a seismic station.
4) 4 min
3. The epicenter of an earthquake is located 6,500 kilometers away
from a seismic station. If the first S-wave arrived at this seismic
station at 1:30 p.m., at what time did the first P-wave arrive?
1) 1:20 p.m.
2) 1:22 p.m.
3) 1:38 p.m.
4) 1:40 p.m.
4. The cross section of Earth below represents a P-wave moving away
from an earthquake epicenter. Seismic station A is shown on Earth's
surface.
Approximately how long did the earthquake's P-wave take to arrive
at the seismic station?
1) 3 min 40 sec
2) 11 min 5 sec
At station A, the first P-wave arrives 11 minutes 40 seconds after the
earthquake. How long after the first P-wave arrives will the first S
-wave arrive?
1) 5 minutes 00 second
2) 8 minutes 40 seconds
3) 9 minutes 40 seconds
4) 21 minutes 20 seconds
5. What is the approximate time difference between the first -wave
and the first -wave recorded at a seismic station located 8000
kilometers from an earthquake’s epicenter?
1) 8 minutes 40 seconds
2) 9 minutes 20 seconds
3) 5 min 10 sec
4) 6 min 20 sec
7. An earthquake occurs at 12:02 p.m. A seismic station records the
first S-wave at 12:19 p.m. Which set of data shows the approximate
arrival time of the first P-wave and the distance to the epicenter?
1)
2)
3)
4)
12:19:40 p.m. and 6000 km
12:11:25 p.m. and 6000 km
12:11:25 p.m. and 4000 km
12:19:40 p.m. and 4000 km
3) 11 minutes 20 seconds
4) 20 minutes 40 seconds

8. Which seismogram was recorded approximately 4,000 kilometers from an earthquake epicenter?
1)
3)
2)
4)
Base your answers to questions 9 through 11 on the diagram below,
which represents seismic stations A, B, and C. The distance from
each station to an earthquake’s epicenter is plotted.
11. The difference in arrival time between the P-wave and the S-wave
recorded at a seismogram at station B was 4 min. and 40 sec. What
was the distance in kilometers of this earthquake epicenter from
station B?
1) 3,200 km.
2) 1,200 km
3) 4,000 km
4) 2,400 km
9. The epicenter is closest to point
1) G
2) E
3) F
4) D
10. The P-wave of an earthquake originating 2,600 kilometers from
seismic station A arrived at 5:24:45 a.m. What was the arrival time
of the S-wave from the same earthquake?
1) 5:21:05 a.m.
2) 1:24:45 a.m.
3) 9:24:05 a.m.
4) 5:28:45 a.m.
